Virginia Index of Performance incentive program; raising the achievement of students in proficiency gap groups. Adds to the existing Virginia Index of Performance incentive program guidelines the requirement that the Board of Education recognize and reward all schools and school divisions that make significant progress toward raising the achievement of students in the English language learners subgroup, students with disabilities subgroup, economically disadvantaged students subgroup, African American students subgroup, or Hispanic students subgroup, identified pursuant to the Elementary and Secondary Education Act of 1965 (ESEA) while narrowing gaps in achievement among all student subgroups identified pursuant to ESEA. The bill also requires the Board of Education to take into account in its guidelines improvements of at least two letter grades from the previous school year in the English language learners subgroup, students with disabilities subgroup, economically disadvantaged students subgroup, African American students subgroup, or Hispanic students subgroup; higher than average participation in advanced testing in any such student subgroup; and an annual increase in the percentage of students in kindergarten through second grade, in any such student subgroup, who meet the benchmark on the Phonological Awareness Literacy Screening (PALS) assessment.
